we want to show you live pictures from capitol hill where president obama will speak this hour at the unveiling of a statue of civil rights pioneer rosa parks, the first of an african-american woman to stand in the capitol statuary hall. parks became an icon in 1955 after refusing to vacate her seat to a white passenger on a bus in montgomery, alabama. that act of defiance resulted in her arrest and a bus boycott led by a pastor named martin luther king. not far from the capital the supreme court is hearing arguments on a key provision on whether the 1965 voting acts law has outlived its productivity it is considered one of the most effective and powerful civil rights statutes in american history. in the high court bulls eye is section five which requires nine states with a history of discrimination to clear any proposed change in voting rules with the federal government. it also partially covers districts in seven other states. the act was reauthorized in 2006. democrats from the hill held a news conference late this morning on the steps of the court to call for section five to be up
